- In this study, we present a eccentric end-to-end path selection and recovery scheme that guarantees fast and efficient recovery of individual and groomed paths in Generalized Multiprotocol Label Switching (GMPLS) based Wavelength Division Multiplexing (WDM) networks. To this, we propose a novel allocation and restoration strategy called "Reverse Shared Risk Link Group (RSRLG)" and demonstrate how this concept can be applied to minimize network reconfiguration in GMPLS networks and to minimize network recovery time. It is found that only a additional open shortest path first-traffic engineering (OSPFTE) message is needed to support the RSRLG scheme and a very fast restorability can be accomplished for a single failure. This paper also has developed an analytical model and performed analysis for the proposed scheme in terms of two performance factors: mean number of recovery requests in the system and recovery blocking probability. © Springer-Verlag 2004.
